DIY easy bubble blower - made with empty water bottle! The kids loved it! There was a "fight" over a larger water bottle until the kids discovered you can make longer bubble "tails" with a smaller bottle (requires less air to blow).
free tires from garages more then willing to give them away. A few cans of spray paint from Walmart (paint after assembled to save on paint) and Cypress mulch (packs really nicely) from Home Depot. Adding in a Little Tikes sliding board.
